Prostate cancer is is the most common solid neoplasm and it is now recognized as one of the most important medical problems facing the male population. Due to its long latency and its identifiable preneoplastic lesions, prostate cancer is an ideal target tumor for chemoprevention. Different compounds are available and certainly polyphenols represent those with efficacy against prostate cancer. This review take a look at activity and properties of major polyphenolic substances, such as epigallocatechin-3-gallate, curcumin, resveratrol and the flavonoids quercetin and genistein. Although the current studies are limited, mechanisms of action of polyphenols added with the lack of side effects show a a start for future strategies in prostate chemoprevention.
Objective: To evaluate the efficacy of Profluss® on prostatic chronic inflammation (PCI). Materials and Methods:We prospectively enrolled 168 subjects affected by LUTS due to bladder outlet obstruction submitted to 12 cores prostatic biopsy for suspected prostate cancer + 2 cores collected for PCI valuation. First group consisted of 108 subjects, with histological diagnosis of PCI associated with BPH and high grade PIN and/or ASAP, randomly assigned to 1:1 ratio to daily Profluss® (group I) for 6 months or to control group (group Ic). Second group consisted of 60 subjects, with histological diagnosis of BPH, randomly assigned to 1:1 ratio to daily Profluss® + α-blockers treatment (group II) for 3 months or to control group (group IIc). After 6 months first group underwent 24 cores prostatic re-biopsy + 2 cores for PCI while after 3 months second group underwent two-cores prostatic for PCI. Specimens were evaluated for changes in inflammation parameters and for density of T-cells (CD3, CD8), B-cells (CD20) and macrophages (CD68). Results: At follow-up there were statistical significant reductions of extension and grading of flogosis, mean values of CD20, CD3, CD68 and mean PSA value in group I compared to Ic, while extension and grading of flogosis in group II were inferior to IIc but not statistical significant. A statistically significant reduction in the density of CD20, CD3, CD68, CD8 was demonstrated in group II in respect to control IIc. Conclusions: Serenoa repens+Selenium+Lycopene may have an anti-inflammatory activity that could be of interest in the treatment of PCI in BPH and/or PIN/ASAP patients.
ObjectiveTo determine the relationship between lower urinary tract symptoms (LUTS)/benign prostatic hyperplasia (BPH) and 10-year risk of cardiovascular disease (CVD) assessed by the Framingham CVD risk score in a cohort of patients without previous episodes of stroke and/or acute myocardial infarction. Patients and MethodsFrom September 2010 to September 2014, 336 consecutive patients with BPH-related LUTS were prospectively enrolled. The general 10-year Framingham CVD risk score, expressed as percentage and assessing the risk of atherosclerotic CVD events, was calculated for each patient. Individuals with low risk had ≤10% CVD risk at 10 years, with intermediate risk 10-20% and with high risk ≥20%. Logistic regression analyses were used to identify variables for predicting a Framingham CVD risk score of ≥10% and moderate-severe LUTS (International Prostate Symptom Score [IPSS] ≥8), adjusted for confounding factors. ResultsAs category of Framingham CVD risk score increased, we observed higher IPSS (18.0 vs 18.50 vs 19.0; P < 0.05), high IPSS-voiding (6.0 vs 9.0 vs 9.5; P < 0.05) and worse sexual function. Prostate volume significantly increased in those with intermediate-vs low-risk scores (54.5 vs 44.1 mL; P < 0.05). Multivariate logistic regression analysis showed that intermediate-[odds ratio (OR) 8.65; P < 0.01) and high-risk scores (OR 1.79; P < 0.05) were independently associated with moderate-severe LUTS. At age-adjusted logistic regression analysis, moderate-severe LUTS was independently associated with Framingham CVD risk score of ≥10% (OR 5.91; P < 0.05). ConclusionOur cross-sectional study in a cohort of patients with LUTS-BPH showed an increase of more than five-fold of having a Framingham CVD risk score of ≥10% in men with moderate-severe LUTS.
Study Type – Aetiology (case series) Level of Evidence 4 OBJECTIVES To investigate a possible association between the severity of lower urinary tract symptoms (LUTS) and the serum levels of sex hormones in men with symptomatic benign prostatic hyperplasia (BPH) that underwent surgery for severe benign prostatic obstruction. PATIENTS AND METHODS In all, 127 selected men with symptomatic BPH attending our urology clinic were recruited. The clinical conditions of BPH were assessed by digital rectal examination, serum prostate‐specific antigen (PSA) determination, International Prostate Symptom Score (IPSS), transrectal ultrasonography and maximum urinary flow rate (Qmax) value at uroflussimetry. Before surgery, we measured the serum concentrations of total testosterone (TT) and free testosterone (FT), oestradiol, prolactin, luteinizing hormone and follicle‐stimulating hormone. We excluded men with endocrine diseases, those with prostate disease who were receiving antiandrogen therapy and those with psychological diseases. The relationships between the IPSS score and serum sex hormone levels were determined. RESULTS The final study population consisted of 122 men (mean age of 70.66 years), as five were excluded (three due to incomplete evaluation and two who were diagnosed with prostate cancer). On statistical analysis, the total IPSS was significantly associated with age (r= 0.405, P < 0.001) and TT (r= 0.298, P= 0.020) but not with FT or the serum levels of the other sex hormones. The serum levels of testosterone and IPSS did not correlate with prostate volume and Qmax. PSA level and age correlated with prostate volume (r= 0.394, P < 0.001; r = 0.374, P < 0.001, respectively). We distinguished two subgroups of patients: the first group of 40 men with an IPSS of <19 and the second group of 82 with an IPSS of >19, and we evaluated the median levels of TT in each group. There was an increased risk of LUTS in men with a greater serum concentration of TT (P= 0.042), although the mean TT level was in the normal range. CONCLUSIONS In the present study, the severity of LUTS was associated with age and serum levels of TT but only age correlated with the measures of BPH, especially prostate volume. The potential effects of testosterone on LUTS may well be indirect. Additional large studies are needed to confirm these preliminary results.
The aim of this study was to evaluate the efficacy of the association of intralesional verapamil (ILV) injection with oral antioxidants compared with ILV monotherapy in patients with early onset of Peyronie's disease (PD) at 12-week follow-up. Group A (n = 52) received ILV 10 mg weekly for 12 weeks, while group B (n = 53) received ILV 10 mg weekly for 12 weeks + antioxidants orally one tablet once a day for 3 months. The main efficacy outcomes were the change in plaque size (PS), penile curvature (PC), visual analogue score (VAS), IIEF-15 and IIEF-15 subdomains. Both groups showed significant improvement from baseline to week 12 relative to PS and PC, while group B also in IIEF-15 score (mean difference: 5.51, P < 0.01) and VAS (mean difference: -2.71, P < 0.01). No significant differences were observed between both groups in PS and PC. Finally, both groups showed significant increase in orgasmic function (IIEF-OF) and overall satisfaction (IIEF-OS), while group B showed significant improvement also in intercourse satisfaction (IIEF-IS). Significant differences were found relative to IIEF-OF, IIEF-IS, IIEF-OS and VAS scores in the group B compared with group A. Patients affected by PD may benefit from combination treatment with ILV and oral antioxidants thanks to the improvement in IIEF-OF, IIEF-IS and IIEF-OS at 12 weeks.
